OIL-PRESS.

SYPECIFIGATION forming part-of Letters Patent No. 621,897, dated March28, 1899. Application filed Au ust; 5,1898. Serial No. 687,873. (lilomodel.)

To all whom it 777 601] concern:

Be it known that we, WILLIAM P. CALLA-' use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

Our invention relates to improvements in presses for extractingvegetable oils; and it has for its object the provision of means forkeeping thepress-boxes in proper position at all times, to provideconnections between the several press-boxes that will not be liable todisconnection, and to strengthen the supports for the walls of thepress-boxes.

The first of these objects is accomplished by uniting the columns withthe press-plates and lower cast-iron ram-block in such manner as to makeit impossible for the said plates and block to move laterally orlongitudinally.

The second object is accomplished by means of double-headed links thatare secured in slots in each two of the steel press-plates, thusdispensing with the use of nuts.

The third object is accomplished by providing grooves in the lower sidesof the press plates into which the side walls are fitted and whereby agreat portion of the strain on said walls is taken off of theconnecting-rivets.

A still further object of the invention consists in constructing theoil-channels in the steel ram-block in such manner that the oil will notbe obstructed by the end wall when the press-boxes are elevated byhydraulic power.

Referring to the accompanying drawings, Figure 1 is an elevation of alower portion of an oil-press having ouriinprovements. Fig. 2 is asection on the line a: 00 of Fig. 1. Fig. 3 is an enlarged view of acorner of one of the steel press-plates. Fig. at is a longitudinalmid-sectional view of a press-box. Fig. 5 is a plan View of a press-box,parts being broken away. Fig. 6 is a transverse section through onepress-box and an end elevation of an adjacent press-box.

Fig. 1 contains threepress-boxes in an operative position. These boxesare more clearly 5 5 illustrated on Sheet No. 2 of the drawings, towhichreferenceismade. Thesteelram-block A is. cut from a single piece ofmetal and has a series of longitudinal oil-channels a, which terminateat one end of the block in downwardly-extending oil-channels a, thelatter being continuations of the channels a. These down-channels a arecut into the end of the block a distance substantially as shown in Figs.4 and 5. By thus cutting the channels a said channels lie in from theextreme end of the block and are inclosed on each side by division-wallsa". The walls B, that inclose that end of the blocks when the boxes aremoved upward by the application of power, will therefore not obstructthe fiow of oil from the ram-block channels (I. The an gle-bars B,forming the walls B of the boxes, fit i'n flat grooves c in the lowersides of the steel pressplates 0 and are secured to said plates byrivets D. The outward pressure against these walls 13 is so great thatordinary means of attaching have been found inadequate. To suitablystrengthen the connection of said bars with the press-plates O, the saidplat-es are thus provided with the recesses or grooves c. This greatlystrengthens the construction and prolongs the life of the press. The oilas it is pressed from the meal passes through perforations o in the matE and then enters 8 5 the channels a in the steel ram-block, from whenceit passes to the lower end of the pressplate 0. .When in position in thepress, the press-boxes occupy uniformly inclined positions, the ends Kbeing on the'lower plane.

H is a brass, malleable-iron, or steel plate attached to the lower sideof the steel pressplate 0. Each of the press-plates O has two slots dd,which receive double-headed links G and are closed by plates df,secured by screws 95 e. The links G constitute link connections betweenthe press-boxes of a character that will not become loose, owing totheir described construction. Before the hydraulic pressure is put onthese links form a series of depend- I00 ing connections by which theboxes are sus pended from the uppermost press-plate, this latter platebeing made fast to the press-head (not shown) in a well-known manner.This is an important feature of the invention, as thereby a commonannoyance, due to the loosening of nuts and dropping out of the bolts,is avoided. The press-plates O are f urther provided with four channelsf near the corners to receive the feathers g on the presscolumns M. Thesaid plates are by these means kept from any lateral or longitudinalmovement. The lower cast-iron ram-block I receives the oil from theplates 0. Besides that flowing through the channels ct a, the oilfinding its way to other parts of the steel press-plates will also becaught by the said cast-iron ram-block I, from whence it dischargesthrough nozzle I. The lower cylinder J has an upturned rim J andupwardlyprojected open bosses J. Any oil finding its way to saidcylinder will be confined therein by the rim J and bosses J. Leadingfrom the opening in the bosses are key-slotsj, into which the feathers gon the columns M fit.

O and O are angle-irons secured to the upper sides and end of thepressplates O to confine the oil and direct it to the discharging endsof said plates.

From the above description it will be seen that the press is verycompact and that it is impossible for the boxes to get out of alinement.

Having described our invention, we claim 1. In an upright oil-press, thecombination with a series of press-plates, of a series of ram-blockseach of which has a series of longitudinally-arranged oil-channels aterminat- 2. In an oil-press, the combination with a press-plate O, of aram-block having a series of longitudinal oil-channels terminating atone end in down-channels that lie in, a distance from the end of saidblock, and an angle-bar, one side of said bar forming an inclosing wallfor the end of the block having the down-channels, the other side beingconnected to the plate 0, substantially as specified.

3. In an oil-press, a press-box comprising a ram-block havinglongitudinal oil-channels terminating in down-channels at one end thatlie in, a distance from the said end, a pressplate upon which saidram-block is supported, the said press-plate having flat grooves in itslower side, angle-irons fitted in said grooves and secured to the saidplate, the said angleirons forming the walls around the ram-block, and aperforated mat above the ram-block, substantially as described.

4. In an oil-press, two or more press-plates provided with openings neartheir corners, the said openings extending from the edge of the platesinwardly, side plates closing said openings, and links inclosed in saidopenings and constituting connections between said plates, substantiallyas described.

5. In an oil-press, the combination ofa ramblock having longitudinaloil-channels terminating at one end in down-channels that lie in fromsaid end, a press-plate having grooves c in its lower side, and slots (Zand f in its edges for the purposes specified, and angle-irons securedin said grooves c, and

forming walls inclosing the adjacent ramblock, substantially asdescribed.

In testimony that we claim the foregoing as our own we hereto affix oursignatures in presence of two witnesses.
